Description
The measurement of prompt and non-prompt $J/\psi$ in heavy-ion collisions provides a powerful tool to probe the dynamics of the hot, dense plasma formed in heavy ion collisions at the LHC. Prompt $J/\psi$ probe the effects of color screening, color recombination, and potential new phenomena. Non-prompt $J/\psi$'s serve as a proxy for $b$-quark systems produced in these collisions, and their behavior primarily reflects that of the produced $b$ quarks. The azimuthal distribution of $J/\psi$ relative to the event plane estimated with forward-going particles and their energy deposit on the calorimeters, provides complementary information to the $R_\mathrm{AA}$, offering clues about the stage at which charmonium states are formed during the system evolution, and thus providing insights on the factors affecting its production. On this poster, ATLAS will present its first measurements of the elliptic flow of prompt and non-prompt charmonia in intervals of transverse momentum, rapidity and centrality.
